250 Part IIT.—Nineteenth Annual Report 
to add another station for it—viz., Loch Eil (off Loch Linnhe)—where it 
was dredged along with Cletodes monensis and Cletodes perpleza on April 
3rd, 1900. 
Pseudothalestris major (T, and A. Scott). 
This somewhat rare species was obtained in the store-pond of the Sea- 
Fish Hatchery at Bay of Nigg in August, 1900. 
Cervinia bradyi, Norman. 
This interesting and well-marked species was obtained in the same 
gathering with Cletoiles monensis referred to above, collected 13 or 14 
miles north-east of Buckie, Moray Firth, in 50 to 55 fathoms, November 
3rd, 1900. This is the second time that Cervinia has been taken in the 
Moray Firth ; it was taken the first time about five to seven miles off 
Rosehearty, in 1893, and at that time it was also associated with Cletodes 
monensis, 
Zaus goodsirt, G. 8. Brady. 
This fine species was collected in 45 fathoms off Aberdeen, on 
November 7th last year, by the Fishery steamer “Garland.” The 
gathering in which the Zaus goodsiri occurred contained a remarkable 
assemblage of rare and interesting Crustacea ; they comprised nearly fifty 
species, and included many genera, and nearly all the more important 
groups were represented—viz., the Copepoda, Amphiphoda, Isopoda, 
Sympoda, Schizopoda, and the Macrura. 
Peltidium purpureum, Philippi. 
This species was added to the British fauna in 1886; it was obtained 
at Tarbert, Loch Fyne, during some investigations carried on there under 
the direction of the Fishery Board for Scotland. Though Peltidiwm 
purpurewm has since that time been observed in one or two other parts of 
Loch Fyne and the Clyde estuary, it does not appear to have been 
recorded from any other district of Scotland. In the present paper, 
however, I am able to add two new stations for this Peltidiwm, both of 
which are on the West Coast—viz., Loch Etive, off Abbot’s Island, in a 
gathering dredged at 9 fathoms on March 30th, 1900, and in a gathering 
collected a few days later at from 8 to 10 fathoms near the head of Loch 
Kil (off Loch Linnhe). Both these gatherings were collected by the 
‘“‘ Garland,” and forwarded to the Laboratory at Bay of Nigg 
Alteutha purpurocincta, Norman. 
This fine species was collected in Lerwick Harbour, Shetland, by the 
steam trawler ‘“‘ St. Andrew,” October 14th, 1900. Rev. A. M. Norman 
collected this species at Hiliswick, Shetland, in 1868.* 
Idya cluthe, T. Scott. 
This species, which appears to be a deep-water form, was described in 
1899 from specimens which had been obtained in Loch Fyne at from 50 
to 70 fathoms, and in the Clyde at over 40 fathoms.¢ The same species 
of Idya was recently observed in a tow-net gathering from the Moray Firth
